Mew (FCO 29). Persian (UNB 148). These two cards (Mew and Persian) in conjunction with amazing rare Yveltal allow for the player to use the "Amazing Destruction" attack for zero energy even though Mew does not "have" the attack "Caturday" nor "Amazing Destruction". It is only allowed to used them per the ability. This makes Mew able to OHKO anything from turn 2 on for free which is not how the abilities should interact. This needs to be addressed immediately or the Expanded format will be completely unplayable.

[D-Babs]: Is it a bug?
[Skyjet478]: idk it has to work or maybe is a bug
[D-Babs]: How does it make any sense that this is how the abilities are supposed to work?
[Skyjet478]: but mew says it can use all attack and persian remove all energy if u have caturday
[D-Babs]: So...
TURN TIMER: a Timeout Allowance was consumed to add 60 seconds to turn time
[D-Babs]: Meowth doesn't have the amazing desctuction attack
[Skyjet478]: but mew has
[Skyjet478]: and is also has caturday
[D-Babs]: No, this is a bug.
[D-Babs]: It doesn
[Skyjet478]: but the ability let me have it
[Skyjet478]: so it doesnt count?
TURN TIMER: a Timeout Allowance was consumed to add 60 seconds to turn time
[D-Babs]: It doesn't "have" the amazing destruction attack, the ability allows you to use it but that is different than "having the attack"
[D-Babs]: I think it is a seriously messed up bug
[D-Babs]: And now I can't play expanded format anymore
[D-Babs]: So....
[Skyjet478]: persian says has the attack caturday
[D-Babs]: this client is becoming more and more painful to use now.
TURN TIMER: a Timeout Allowance was consumed to add 60 seconds to turn time
[Skyjet478]: oh wait ur true
[D-Babs]: Yes, mew doesn't "have the attack caturday", it just "can use" the attack
[D-Babs]: so....
[Skyjet478]: yeah it should be a bug sad
[D-Babs]: Mew only "has" one attack
TURN TIMER: Your turn will end in 6 seconds
